CHASE - Commercial Human Spaceflight Expeditions

In the 2021 Fall term, the ASTE Studio focused creative efforts on how commercial human spaceflight in the United States could catalyze space activity around the globe and steer the future of human spaceflight. With an eye on NASA's Gateway and Artemis projects, the CHASE project cast the net wide, to seek out synergies and collaborations sans policy limitations. By starting to explore the future of governmental and commercial activities in low Earth orbit, on the International Space Station, and evolving outward to encompass cislunar space and our Moon, the USC CHASE project imagined and created potential concepts that we feel are worthy of further investigation. Topics explored included Commercially focused Utilization of the International Space Station, Uses of a Human-tended Geostationary Space Station, Evolution and Uses of an Advanced Cislunar Communications Infrastructure, Importance of Establishing a sturdy Earth-Moon Logistics Channel to support 21^st century cislunar traffic and a permanent human lunar surface presence. A scientific exploration mission for the Artemis lll crew to retrieve solar activity records to help build a much more complete solar behavior model over geologic time that can inform Climate Change on Earth and also explore the interior of a lunar lava tube, a concept for a Robot scout assistant rover for lunar surface crew in EVA, and Crew safety and rescue Infrastructure establishment before commencing Artemis missions that can also be used in case anomalies arise are proposed as well as the evolution of nuclear power systems for lunar applications. Several American space companies are sprouting that continue to broaden human spaceflight capability and expand CHASE allied engineering capacity needed to grow and mature this fully homegrown space industry ecology. Powered by the plummeting costs of components and methods like advanced additive manufacturing, a wide stable of launchers and private spacecraft are entering the space activity domain once considered the monopoly of governments. Commerce is the lifeblood of modern civilization. Healthy competition and agility, ingenuity and innovation are the drivers of economics and profit in this sector. We must continue to encourage real space commerce, especially human space activity, beyond the NASA vendor-buyer model. Fundamental economic sense drives all successful commerce. A sustainable business model requires a profit motive. [Profit = Revenue - Cost] is a fundamental formula for all sensible commerce. Monitoring and minimizing environmental impact is a prime concern in the fragile vacuum and weightlessness of Space. All these CHASE related activities, both domestic and around the globe bode well for the US to remain the beacon of the free world and at the forefront of space activity. Human space activity in particular, makes us the nexus for global cooperation and collaboration. That is a good sign for 21st century civilization, progressing step-by-step to build a peaceful, equitable and glorious future for humanity in space and on Earth. Synopses of visions created in the CHASE concept studio are presented. Recommendations are made. Welcome to USC ASTE527 2021 CHASE Graduate Space Concept Synthesis Studio dear colleagues, where architectural and engineering minds work together to imagine the “what can be” of human spaceflight.
